T 0 all whom it may concern Be it known that I, ARTHUR B. a citizen ofthe United States, residing at New York, in the county and State of NewYork, have invented a new and useful Air Compressor, of which thefollowing is a specification.

This invention relates to air compressors, and especially to that classwhere the air is compressed by water; and the objects of my inventionare to provide an air compressor so constructed that the air will becompressed by flowing water in a stand pipe, or conduit, to providemeans to introduce the air into the flowing water; to provide for theproper division of the stand pipe, or conduit where the water and air isto flow in one direction and the water alone in the other; to providemeans to keep the ascending column of water at a lower level than thedescending column; to provide means to strengthen the stand pipeJENNINGS,

if desired; to provide suitable means for the extraction of thecompressed air from the descending column of water.

The invention is illustrated in panying drawings in which- Fig. l, is asectional elevation of the air compressor constructed in accordance withmy invention, a part being shown in full lines, a part diagrammatically,and a part fragmentarily. I

Fig. 4, is a view similar to Fig. 1, showing a modified form ofconstruction.

Fig. 5, is a transverse section of the same on the line 55 of Fig. at, apart being shown in full lines and a part fragmenta rily.

the accom- Fig. 6, is a partial transverse section on the line 6-6 ofFig. 4.

Fig. 7 is a view similar to Fig. 1, show- I in another modified form ofconstruction.

ig. 8, is a transverse section thereof, on the line 8-8 of Fig. 7, and

Fig. 9, is a transverse section on the line 99 of Fig. 7.

In the drawings, like letters of reference refer to the same parts ineach of the views. In practice I provide for the product1on ofcompressed air in a stand pipe or conduit by utilizing one ofconsiderable helght,

umn of water descending and insuring the rapid flow of water through thesame.

In Fig. 1, I'have shown a stand pipe P preferably of great lengthdivided by a partltion T into two longitudinal compartments H, and H*,the compartment H being the larger in area for purposes hereinafterexplained.

To maintain water in at a higher level than in the compartment H I mayemplo a pump A of any desired construction, to ift the water from thetop If in this compartment to the top I in the compartment H. Or thecompartment H may be fed from a reservoir B in a manner to maintain thewater at a higher level in the compartment H than in the compartmentH,-a conduit C being provided to permit the water to flow from thecompartment H so that the flow of water down the compartment H in arapid manner will be assured. It will be understood, of course,that'b'oth the pump A and the reservoir B may be employed simultaneouslyto ensure a rapid flow of water through the compartments. Air may beintroduced into the colin the compartment H in any desired manner. Itmay be introduced by inclined pipes G, or by a fan F or by both ifdesired and it stood that the water scendin column will carry with itconsiderable air, and the water flowing into the de scending column fromthe reservoir will also carry considerable air.

As the water descends in the pressure will be increased by the water;and the contained air will be forced out by this pressure as well ascompressed to a considerable extent thereby. To catch the comp artment Hcolumn H, weight of will be underpumped into the dethis compressed air Ihave provided the inverted pockets D, which will be atvarious heights toallow space for water to flow past them, and are spaced apart so thedescending water can flow inwardly between the ment to allow for thenatural contraction of the water in falling, thereby providing means forthe more certain extractlon of the I tained and the pipe J.

ascending ipes should belniaintainedat,

height I may provide means for reinforcing, or strengthening the bottom.pets. shownin Fig. l the bottom of the pipe P is strengthened with coilsof wire W, wound around the pipe in the manner well known.

It wiltbe observed. thatlthe partition T as shown in Fig. 2 differs fromthe partition T" shown in Fig. 3, as one is angled and the other is not.The angling of the partition maybe used in the lower part of the tube toreduce the size of the compartair give the descending column a greaterarea than the ascending column, owing to the fact that this columncontains considerable air but as the column in compartment H continuesto descendTthe air is gradually. forced out so that at the bottomfoi'the pipe the partition '1 may occupy the exact centre of the pipe. y y aFig. 1 shows my invention as applied to a single pipe. It is evident ofcourse that two or more p pes mightbe used butit is deemed desirablethat the pipescontaining the descending water should be greater area atthe topthan the pipe or pipes containing; the ascending water. Thus, by

making the compartment containing air and water larger than thecompartmentcontarn:

ing only water, provision is ma'defor the volume of air carried in, thecompartment. It is important, though,,that the-water in the lower levelthe watenin the descending secure the compressed air at any point depipe, or pipes,thereloy insuring a rapid flow in order to carry theqairwith thewater in its descent, orflow throughfthe pipe, or

simple and efiective means to secure, compressed air from flowing waterbypressmg the air out of the same as the water; descends,

and by providing for the rapid: how of in. any desiredplace, in, theshafts of deep m1nes,orin other suitable locations, and

sired, and for any desiredpurpose.

In Figs. 4,5, and6, Ihave shown amodified form of construction in whichluse a pipe P oblong in form intcros's sectiongas shown, which may bedividedwith alpai tition T into substantially two; compart-. ments H andH w a I In this construction a plurality of air pockets .1) are mountedin the descending column as well asa pocket E atthe bottom. The airgathered by the pocketsD! and E are led to atank K by pipes J. Imayintroduce it the top of the pipe "a is desirableto It will thus be seenthat Ihave;,p.rovided;

ing strips O as clearly shown on Figures 4: and 5.

In Figures 7, 8, and 9 -I have shown another modlfied form ofconstruction in which I have provided two pipes P and P for thedescending and assembling columns of water respectively. The tank K isre- 1. An air compressor comprising a de scendlng, and an ascendingcolumn of water,

said columns being in communication at both top and bottom, means tointroduce air and water into one column, means to maintain the water ata lower level in the other column, and a plurality of pockets arrangedat intervals in the adapted to receive air from the flowing water, saidpockets being spaced apart and arranged whereby the water may flow inwardly between said pockets.

2;. An aircompressor comprising compartmentsadapted to contain ascendingand descending columns of water in communication at both top and bottom,means to introduce air and water intov one compartment means tomaintainthe water at a lower level in the other compartment, and meansto extract compressed air from the descending column of water, saidmeans comprising in, part a plurality of pockets distributed along thedescending compartment, and a pocket located at the juncture between thecompartments at the bottom said pockets being in communication with areservoir.

3. An air compressor comprising a pipe divided into two compartments incommunlcation at top and bottom, means to introduce air and water into.one compartment, means tokeep the water at a lower level in the othercompartment, and means to extract compressed air from the descendingcolumn of water, said pipe being divided by a partition angled part ofits lengthnvhereby the descending column of water is provided with asmaller compartment. at the bottom than at the top.
